Students observe a partial graph of seismic data produced from an earthquake. The graph shows data for two different layers in earth. The students create a table to identify which layers are shown in the graph. Which table BEST represents the data in the graph? (answers are in image)

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.
